Rough Welo opal, main mineral Opal, rugose form, 25 g, from PEGOMAS, Ethiopia.
AI-assisted summary
Description from the seller
Lot of 25 grams of raw Welo Opal in a box
Weight (from lightest to heaviest): 0.95 to 2.90 grams
Size (from smallest to largest): 1.8 to 3.0 centimeters
You are purchasing the opals as pictured (the opals have not been wetted for the photos)
Shipped with an invoice acknowledging my professional responsibility
All my coins, medals, fossils, meteorites and others are guaranteed authentic and come from private collections or professional dealers in compliance with the law.
Welo Opal is found in silica veins just 2-3 meters below the surface. What makes its mining so difficult are the means used. Only the inhabitants of this region are allowed to exploit these deposits. The rural populations use archaic and sometimes dangerous methods to extract the stones. Since January 2011, a new mining site has emerged with stricter standards, bringing together 500 professional miners. The Ethiopian government regulates and monitors this wealth by not allowing buyers to go to the mining sites to deal directly with the miners. The Opal market is located outside the mining region.
Welo Opal is often hydrophane. Indeed, when immersed in water it can become completely translucent, only to regain its original appearance as it dries. The drying process should not be accelerated; it can take several days.
